Second order proton traps for multi-nuclear RF coils: Applied for 13C MRS in humans at 7T

Rolf Gruetter

The concept of second order proton traps (consisting of an inductor and two capacitors) in coils for non-proton NMR allows control over the resonance frequency, the blocking frequency and the trap mode frequency. Effective proton traps with relatively high ...

Line-narrowing in proton-detected nitrogen-14 NMR

Geoffrey Bodenhausen, Simone Cavadini, Simone Ulzega

In solids spinning at the magic angle, the indirect detection of single-quantum (SQ) and double-quantum (DQ) N-14 spectra (l = 1) via spy nuclei S = 1/2 such as protons can be achieved in the manner of heteronuclear single- or multiple-quantum correlation ...

Transverse Relaxation of Scalar-Coupled Protons

Geoffrey Bodenhausen

In a preliminary communication (B. Baishya, T. F. Segawa, G. Bodenhausen, J. Am. Chem. Soc. 2009, 131, 17538–17539), we recently demonstrated that it is possible to obtain clean echo decays of protons in biomolecules despite the presence of homonuclear sca ...

Mannich products of kojic acid and N-heterocycles and their Ru(II)-arene complexes: Synthesis, characterization and stability

Paul Joseph Dyson, Christian Hartinger, Alexey Nazarov

Ru(II)-η6-p-cymene compds. bearing pyrone-derived ligands, which were obtained by Mannich reactions between kojic acid and piperidine or morpholine analogs, have been synthesized. The compds. were characterized by NMR spectroscopy, mass spectrometry, therm ...

, ,

Full signal intensity H-1-[C-13] NMR spectroscopy, combining a preceding C-13-editing block based on an inversion BISEP (B-1-insensitive spectral editing pulse) with a spin-echo coherence-based localization, was developed and implemented at 14.1 T. C-13 ed ...

Osmium(II)-versus ruthenium(II)-arene carbohydrate-based anticancer compounds: similarities and differences

Paul Joseph Dyson, Christian Hartinger, Alexey Nazarov, Muhammad Hanif

The synthesis and in vitro anticancer activity of OsII-arene complexes with carbohydrate-derived phosphite co-ligands are reported. The compds. were characterized by std. methods and the mol. structure of dichlorido(η6-p-cymene)(3,5,6-bicyclophosphite-1,2- ...

Improved ¹H-[¹³C] and ¹H NMR methods for in vivo measurement of cerebral metabolism

Lijing Xin

Nuclear magnetic resonance (NMR) spectroscopy can be applied in vivo to measure static or dynamic biochemical information, e.g., concentrations of metabolites and metabolic fluxes, using various nuclei such as 1H, 13C, 31P and 15N. The work of this thesis ...

Effects of homonuclear scalar couplings during multiple refocusing sequences in nuclear magnetic resonance

Nicolas Aeby

Multiple refocusing cycles can be used to extract transverse relaxation rates, R2, while homonuclear scalar couplings do not interfere. In this work, I have demonstrated the usefulness of a hybrid sequence, which is a compromise between single and multiple ...
